In the 17th and 18th Century, the area was inhabited by the Aruã, mainly around the Ganhoão River. Most of them migrated to Amapá and French Guiana after the Treaty of the Mapuá. In 1793, the Portuguese transferred the ones who had stayed to the lower Tocantins River.{{cite book |last=Steward |first=J.H. |date=1948 |title=Handbook of South American Indians, Volume 3: The Tropical Forest Tribes |url=https://etnolinguistica.wdfiles.com/local--files/hsai:vol3p193-198/vol3p193-198_turiwara.pdf |location= |publisher=Smithsonian Institution |page=194–196 |isbn= |access-date=}} On the coast of Chaves, ceramic fragments related to them could still be found, but the advance of the Vieira Grande Bay washed them away.{{cite web |author-last=Carvalho |author-first=P.M. |date=2010 |title=Tem quilombo na Amazônia |url=https://www.academia.edu/50997045/Carvalho_2010_Tem_quilombo_na_Amazonia}}
